Precautions
Important Safety Warnings
[Power]
Operate unit only on the specified supply voltage.
Disconnect power cord by connector only. Do not pull on cable portion.
Do not place or drop heavy or sharp-edged objects on power cord. A damaged cord
can cause fire or electrical shock hazards. Regularly check power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
[Grounding]
Ensure unit is properly grounded at all times to prevent electrical shock hazard.
Do not ground the unit to gas lines, units, or fixtures of an explosive or dangerous
nature.
Ensure power cord is firmly plugged into AC outlet.
[Operation]
Do not operate unit in hazardous or potentially explosive atmospheres. Doing so
could result in fire, explosion, or other dangerous results.
Do not allow liquids, metal pieces, or other foreign materials to enter the unit. Doing
so could result in fire, other hazards, or unit malfunction.
If foreign material does enter the unit, turn power off and disconnect power cord
immediately. Remove material and contact authorized service representative if
damage has occurred.
[Transportation]
Handle with care to avoid shocks in transit. Shocks may cause malfunction. When
you need to transport the unit, use the original packing materials or alternate
adequate packing.

[Circuitry Access]
Do not remove covers, panels, casing, or access circuitry with power applied to the
unit! Turn power off and disconnect power cord prior to removal. Internal servicing /
adjustment of unit should only be performed by qualified personnel.
Do not touch any parts / circuitry with a high heat factor.
Capacitors can retain enough electric charge to cause mild to serious shock, even
after power is disconnected. Capacitors associated with the power supply are
especially hazardous. Avoid contact with any capacitors.
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating unit with circuitry exposed could result in electric shock / fire hazards or
unit malfunction.
[Potential Hazards]
If abnormal smells or noises are noticed coming from the unit, turn power off
immediately and disconnect power cord to avoid potentially hazardous conditions. If
problems similar to above occur, contact authorized service representative before
attempting to again operate unit.
[Consumables]
The consumables used in unit must be replaced periodically. For further details on
which parts are consumables and when they should be replaced, refer to the
specifications at the end of the Operation Manual. Since the service life of the
consumables varies greatly depending on the environment in which they are used,
they should be replaced at an early date. For details on replacing the consumables,
contact your dealer.
[Rubber Feet]
If this product has come with rubber feet attached by screws, do not insert the
screws again without rubber feet after removing the rubber feet and screws. It may
cause damage to the internal circuits or components of the unit. To install the rubber
feet again to the unit, do not use other than the supplied rubber feet and screws.

Check
Check to ensure no damage has occurred during shipment. If damage has occurred, or items
are missing, inform your supplier immediately.
Rack Mounting
The DCC-100 can be either single unit or dual unit mounted to EIA standard rack units. Racking
mounting requires purchase of one of the two available rack mount kits.
When single unit mounting the single mount kit with one extended rack ear must be used. When
two units mounting the dual mount kit with standard size rack ears must be used. Consult your
FOR-A supplier to order either of these options.

4. Operation
4-1. Power On
Turn Power switch to ON after all system connections are complete. When the unit is powered
ON, the green Power LED should go on. If either one (or both) of video signals is inputto the unit,
the COMPOSITE IN and/or SD-SDI IN LED shown below will turn on.
4-2. Front Panel Operations
The DCC-100 front panel controls can be used to select video input (INPUT SELECT) and split
display mode (SPLIT).
4-2-1. INPUT SELECT
Set the switch to the upper or lower positions to switch the input video standard.
(When operating with DCC-OUA, change video standard from DCC-OUA.)

4-2-2. SPLIT
Move the switch to upward or downward to select split screen mode for COMPOSITE OUT1,
COMPOSITE OUT2, SD-SDI OUT 1 and SD-SDI OUT 2, which allows direct comparison of
images before and after correction. (When operating with DCC-OUA, change split mode from
DCC-OUA.)
Each time moving the switch up and down changes mode in the sequential order: OFF, 1, 2
and 3.
OFF Displays the image after correction.(Factory default:)
1 Splits the screen vertically and displays images before and
after correction.
2 Splits the screen horizontally and displays images before and
after correction.
3 Displays the image before correction
NOTE
SPLIT mode is OFF whenever you start up the unit.
Split mode can be set separately for COMPOSITE OUT and SD-SDI OUT. To do this,
use the internal dipswitch SW1. SW1-3 switches to enable or disable the split function
for COMPOSITE OUT. SW1-4 switches to enable or disable the split function for
SD-SDI OUT. The factory default is enabled for both. (See section 5-1-1. SW1".)

INPUT
(Default) Minimizes the input/output delay for the selected video signal.
FRAME Synchronizes the frame timing of the output video and reference
input. This setting is effective for input video with a lot of jitter.
If set to INPUT, the delay will be as shown in the table below.
Input video format Signal delay

NOTE
If set to INPUT:
 The amount of jitter on the SD-SDI output depends on that of input signal when
analog composite is selected for input.
 Color framing is not always properly processed for COMPOSITE output when the
SD-SDI input is used.
If set to FRAME:
 The composite input is horizontally locked, however, it is not correctly locked to the
subcarrier of the applied genlock.
 The unit operates in free running mode when no genlock signal is input to the unit.
 SPLIT OFF (Composite OUT) (SW1-3)
Enables/Disables split screen mode (split display for direct comparison of images before and
after correction) for COMPOSITE OUT.
SPLIT OFF Disables split screen mode.
SPLIT ON
(Default) Displays split screen according to the SPLIT switch setting on the front panel. (See section 4-2-2. "SPLIT".)
 SPLIT OFF (SD-SDI OUT) (SW1-4)
Enables/Disables split screen mode (split display for direct comparison of images before and
after correction) for SD-SDI OUT.
SPLIT OFF Disables split screen mode.
SPLIT ON
(Default) Displays split screen according to the SPLIT switch setting on the front panel. (See section 4-2-2. "SPLIT".)
 VITS (SW1-5)
Selects to pass or blank vertical interval data of composite input.
OFF
(Default) Blanks vertical interval data of composite input from 10H to 20H. No vertical interval data is passed to the composite output.
ON Vertical interval data from 10H to 21H is passed to an output. If vertical
interval data is included in the composite input, it is also included in the
composite output.
